GTX 690 has come, but have a problem!

Hey guys, Hope you all have a great christmas.

My GTX 690 has just came in the post this morning. I've had problems trying to fit it however. The card requires two 8 pin power conectors. My computer only has one eight pin and one six pin however.

I've ordered a six to eight pin adaptor but I really want to get it going now. I was wondering if it would be okay if i just plugged in the six pin connector into the eight pin slot on the graphics card. Would that damage my system?

Thanks guys.

  1. It should work with one 8-pin plugged in.

    just a single 8 pin plugged in?
  3. What power supply do you have?
    With one 6 and one 8 pin PCIE connector I doubt it has enough power to power the card.

    No, DO NOT LISTEN TO THIS. It could kill the card.

    I'd wait for the adapter. Better safe than sorry.

    P. S. What is your power supply unit?
  5. Just to put in my opinion. I would not risk trying to turn on such an expensive card in any way besides how it was meant to be powered. Just this summer I blew out two mobos because of a faulty PSU (granted they were old components). My point being, though it is an expensive card, it isn't as durable as you might think, and you will be kicking yourself if something goes wrong before that adapter arrives. I know I probably sound a little rediculous, but better to be safe than sorry! Good luck with that card though.
  6. thank guys. I'm fairly sure my PSU is 750 watt.

    I cant be sure for certain though because there is no label on the side of my psu to tell me.

    Any othe way i can see what my PSU is?
  7. take it out of the chassis and look at all sides... it MUST be on a sticker somewhere - if it's not, then I would purchase a new one because clearly whoever made it did not follow the rules of the road
  8. Wait wait wait no label PSU and you want to use it to power up a $1000 card? Could you please take a picture of it, upload it somewhere (like www.imageshack.us but don't forget to select "do not resize" option), and post the link to the uploaded image here?

    And yes, check all sides of it, definitely.
  9. I originally got the computer from alienware, and my original intention was to have some sort of SLI setup. I'm finding it difficult to take the PSU out of the chassis. I'll post up a picture momentarily.
  10. Personally, that PSU looks "sketchy" at best. If your going to Invest in a 1k GPU, you want the Unit feeding it to be good quality also.

    No sticker.......thats odd
  11. I wouldn't try something like that, as long as that's a 1000$ VGA...
  12. I thought if the PSU was an issue all that would happen would be my computer wouldn't turn on? As far as I knew there is no actual danger of damaging the system by having a PSU that possibly wont be up to spec?

    Thanks for replies all.
  13. It supposed to turn off, But I never trust them lol
  14. it's simple to remove the 4 screws holding in the power supply - then look on the other 2 sides you cannot see from it being in the case, to see if there's a sticker
  15. You should really look at the requirements of your equipment before you buy. This kind of thing happens way too often and it really sucks unless you have a store nearby.

  16. :( Well I can only wait for the adapter to come, and if my PSU's not up to the job I'll have to upgrade.

    Have you taken out the PS and checked all sides for a sticker????????

    Your wrong. If it's a good unit, it will just not turn on. If it doesn't have good protection, it could kill the card and the motherboard. And that's not the worst case scenario - it could catch fire.

    Don't risk it man. At least take it out to read the label first.
  19. hey guys. Ok I've managed to unscrew the PSU and there is indeed a label there.

    I'll write out exactly what it reads:

    ALIENWARE

    MODEL NPS-750AB-1B
    INPUT 100 - 240V -10A, 50-60hz

    OUTPUT
    +12VA -18.0A , +5V - 16.0A
    +12B - 18.0A , -12V - 0.2A
    +2VC- 18.0A , +3.3V - 30.0A
    +12VD-16.0A , +5VPF - 3.0A

    750W MAX

    MAX COMBINED POWER ON +5 AND +3.3 OUTPUT IS 150W

    MAX COMBINED POWER ON +12va, +12VB , 12VC, 1VD OUTPUT IS 700W

    There's a little bit more after this but I don't think it's too relevant. I should also mention I'm running an Intel(R) Core(TM) i7 CPU 965 @ 3.20GHz (8 CPUs), ~3.2GHz processor. And i've got 6134mb ram too. Nothing else is connected that will suck up PSU power.

    Thanks all.

    Edit - the formatting of my post scrambled after i submitted my reply, hopefully you can still make stuff out. Sorry.
  20. i would still say its a little sketchy most computer brands like dell shove the parts in then don't think about you upgrading. I heard about alienware gluing hard drives to the case once
  21. I must say i have used alienware over the past eight years and their quality has always been impeccable.

    I take it from the lack of other responses my PSU will be alright to use.
  22. Well, I was watching a movie :P.

    Anyway, looks good. Just wait for the adapter to come.
  23. I apprecite the help Sunius,

    cheers
  24. No problems, merry Christmas!
  25. Hey guys...

    Okay, the adapter has come and I started the computer up and everything. all seemed fine.

    buuut.

    whenever I play a game my computer now restarts... I put on crysis 2 and maxed everything out, ran like a dream for about 1 minute and then my computer reset. Did the same thing with Saints Row 3. I decided to unmax the settings and i played the game for a good five minutes without any issues. I put the settings up again and played and once again my computer reset itself.

    I've tried with several other games and it's all the same. The reset only seems to occur when the Graphics card is being stressed, which leads me to believe this might be a PSU problem.

    The only game that seems to work on max without making my computer reset is Deus ex human revolution. For some reason I can play on full settings just fine... I find this extremely odd, and makes me think that perhaps it isnt to do with the PSU.

    Thanks for your input guys.
  26. Looks like it. Do you have a friend in whose PC you could try the card (who has an appropriate power supply unit?), so you could know it's the power supply issue?

    If you were to upgrade yours, I'd suggest these ones one:

  27. Hey dude you are taking a big risk running that card on that weak.Unless you want a fried system i suggest you get a decent 800 watt PSU ASAP.

    Some cards do for some reason not speed up the fan(s) properly when being stressed. Get a program like EVGA precision X and set up a fan control profile and you will know for sure it's not the fan.

    I have however had a similar issue with games in general, one of them being crysis 2, and it was not the fan that didn't speed up, it was the power supply. It got worse and worse, eventually the resets happened from watching a movie. Then they happened when I was just browsing the internet. Then one morning the computer didn't even turn on.
